Abstract: A portable in situ psychrometric test apparatus and method for determining, without the use of standard environmental test rooms, the capacity that an air conditioner would exhibit when operated under predetermined standard environmental test conditions. Mutually isolated air flow chambers are detachably mounted to the air intake and air discharge openings of the conditioner. Samples of air flowing through the chambers under normal operation of the conditioner are withdrawn and wet bulb/dry bulb measurements taken at the end of a predetermined operating period. Air velocity through the chambers and condenser environmental air dry bulb temperature are also measured. These measurements give in situ operating capacity which is then converted, using predetermined empirically derived correction factors, to operating capacity under standard environmental conditions.

Abstract: A circuit containing a plurality of fixed detector resistors and a detector potentiometer, each being representative of the contribution to energy consumption of a different operator controllable parameter of an air conditioner and being series connected with one another across a d.c. galvanometer and meter sensitivity resistor. Shorting switches are connected across each of the detector resistors, the conditions of which switches are responsive to the conditions of corresponding switchable parameters such as fan speed, vent door position, etc. A slide arm of the potentiometer is responsive to thermostat operating temperature setting. The resistance values of each detector resistor and the potentiometer are selected to contribute approximately the same percentage resistance to the total resistance of the detectors as a change in the status of its corresponding control parameter contributes to air conditioner operating cost efficiency.

Abstract: The present invention provides an air conditioning system for a mobile home. The system includes securing a mounting means to the support structure of the mobile home and an air conditioning unit that is adapted to be removably secured to the mounting means. When installed on the mounting means, the air conditioning unit is aligned to deliver conditioned air into the interior of the mobile home through its built-in air distribution system.

Abstract: The present invention provides an air conditioning system for a mobile home. The system includes securing a mounting means to the support structure of the mobile home and an air conditioning unit that is adapted to be removably secured to the mounting means. When installed on the mounting means, the air conditioning unit is aligned to deliver conditioned air into the interior of the mobile home through its built-in air distribution system. An interlock system is arranged that is effective in preventing removal of the air conditioning unit from the mounting means when the unit is electrically connected to the mobile home power supply.
